Title: Hand operated feeder for soft solder wire - mounted on soldering iron so only one hand is needed for both feeder and iron
Inventor: PAUNOVIC MLADEN
IPC: B23K3/06
Filed: 1975-06-09
Abstract: The feeder can be mounted on a soldering iron without any modification being required to the iron, and a light finger pressure on the lid of the feeder moves the solder wire towards the joint and also moves a wire guide tube towards the tip of the iron. When the finger pressure is released, the lid and the guide tube return to their original positions. The movement of the wire feeder and the guide tube is achieved by two levers working against spring pressure, whereas another spring is employed to prevent the wire slipping backwards during its forward feed.

Title: Fire alarm with parallel differential maximum heat transmitters - using temp. induced resistance change and differentiating monitor circuit
Inventor: BEYERSDORF HARTWIG ING GRAD
IPC: G08B17/06
Filed: 1975-07-29
Abstract: The fire alarm network of basic circuits depend on the change in value of a resistance, and the rate of that change in value, to detect the presence of a fire. A battery (B) feeds a central alarm circuit (Z) which feeds a number of detector elements (D) connected in parallel between two supply lines (12, 13). The detection elements contain a transistor circuit in which the change in a resistor value (F) when a temp. change occurs, is monitored by a proportional and by a differential circuit, the outputs of which trigger an alarm circuit (A) via an OR gate (V). Any rapid change, or any slow change of sufficient amplitude thus triggers an alarm.

Title: Compressible valve head with internal leakage collector chamber - has outlet pipe from chamber to indicate defective valve seat
Inventor: HEINZ FRANZ
IPC: F16K41/10
Filed: 1975-08-02
Abstract: The shut off spindle valve has a hollow valve cone (10) which is attached to the internal end of the spindle (6). The internal chamber (14) of the valve cone is enclosed by a bellow (12) which allows the valve cone to be axially compressible when the valve is in the closed position. This valve chamber (14) is provided with an outlet tube (16) which ends outside the valve body (4). Any leakage that occurs through the valve seat (13) is collected inside the valve chamber (14). When the chamber is compressed on closing the valve, its internal pressure increases, thus any leakage is forced out through the pipe (16). A defective valve is thus spotted immediately.

Title: Rotary engine with hollow cylindrical piston - has radial vanes creating variable volume chambers with timer controlled poppet valve
Inventor: VEATCH FRANKLIN
IPC: F01C1/356
Filed: 1975-09-19
Abstract: The rotary piston engine has a hollow cylindrical piston (24) rolling inside a casing (20) supporting by a low-friction bearing (56) on an eccentric (54) mounted on a shaft (50) coaxial with the casing. The outside dia. of the piston is 75-95% of the inside dia. of the casing and the whole moving assembly is so dimensioned that, as the piston axis moves in a circular path about the casing axis (32), the min. distance between piston and casing is small. Seals are fitted between the flat end faces of piston and casing, and there are several flat rectangular blades (60) constrained to slide radially in the casing so as to remain in permanent surface contact with the piston. Hence, an uneven number of variable volume chambers is created between piston and casing. Each chamber has poppet inlet (7o) and outlet valves, in a cylindrical part of the casing, operated by a timer on the main shaft (50). A spark plug may be fitted there.

Patent DE-2600889-A1 (DE)
Title: DC generator conductor rotating in radial field - produces steady DC output using homogeneous radial magnetic field with conductors connected in series
Inventor: REINKE REINHARD ING GRAD
IPC: H02K31/00
Filed: 1976-01-12
Abstract: The dc voltage generator, for 200V, 80A produces a dc output which is free from ripple. The output is indistinguishable from the output obtained from a chemical source such as an ordinary battery. This is achieved by rotating a conductor through a radial magnetic field so that it passes through an absolutely homogeneous field and therefore produces no ripple. By connecting such conductors in series voltages of up to 200V can be obtained. The voltage loss across internal resistance can be compensated by a proportionate increase in the excitation current.

IPC: E06B9/382
Filed: 1976-12-24
Abstract: The ladder cord has two side strings (1, 2) which are interconnected by numerous transverse strings (3). The transverse strings consist of two parallel strings, between which the sunshade lamellae (5) are inserted. Each transverse string (3) is provided with a receiving eye (4) for the shade lamellae (5), one end of which is fastened to the side string (1) lying next to the window and which is shorter than the transverse strings (3). Installation of the shade lamellae (5) is made easier by the ends of the eye (4) facing away from the window being interconnected by a string (7). As this string is crocheted, it can be removed again easily after mounting of the shade lamellae by undoing. As the shade lamellae consequently hang in the eyes (4), it is prevented that the side strings (2) facing away from the window are subjected to the weight of the shade lamellae, so that the actuation of the sunshade is made easier by the unloaded side strings (2). Moreover, rubber strips (6) provided on the shade lamellae can, on screening, be brought by the eyes (4) to bear against the respective lower shade lamella. <IMAGE>
